Using the direct stiffness method, determine the reactions at the supports. Draw shear & moment diagrams. Members are axially rigid. While recovering the member internal forces, first use slope deflection equations and then repeat the solution by using element stiffness matrices $($i$.$e$.$ recover the member forces in two different ways$).E=200$ GPa,$I=420{10}^{6}m{m}^4$ for both membrec
